3c64ae7b66 Fix overzealous type merging. 
Use the type name instead of the symbol table for comparing
struct/union/enum types.
 2011-02-07 20:48:01 +09:00
Bill Currie
265a244ba2 Set the symbol type for structs etc as soon as the tag is created. 
Tags (struct/union/enum) are always types.

ef2ad46f7a Convert complex types to a suitable low-level type. 
This takes care of moving structures etc around.

b629c12b31 Do not change the type of the return operand. 
Doing so made a mess of returning expressions. It was probably a holdover
from before getting instructions with void operand types working.

76034861c9 Implement direct ivar access in methods. 
A warning needs to be generated for access to ivars in a class method, but
it seems to work (unable to check due to other errors).
 2011-02-07 08:32:52 +09:00
Bill Currie
3025e04ac5 Partially resurrect field_expr() 
For now, only entity.field and ivar access via a pointer have been
implemented. The rest will come later as needed.

6b7a81f5a7 Run find_type() early on enums and structs. 2011-02-06 20:07:19 +09:00
Bill Currie
d54a96e68a Make enum values visible. 
Put them in the current symbol table as well as the enum symbol table. The
latter is really just for keeping track of what values are in the enum.
 2011-02-06 20:06:09 +09:00
Bill Currie
2860a8b28b enum too is a scalar. 2011-02-06 20:01:55 +09:00

2f7b892452 Fix passing messages to classes. 
Rename class_pointer_def() to class_pointer_symbol() and use it when a
class name is used as the receiver of a message.
 2011-02-06 14:34:40 +09:00
Bill Currie
67957a14df Bring back convert_name(), but siimplified. 
It is now mainly for converting __FILE__ etc, handling expression symbols,
and checking for undefined identifiers.
 2011-02-06 14:29:14 +09:00

d03fdc5e67 Correctly calculate the size of the ivars of a class. 
Need to include the size of the super class ivars.
 2011-02-05 00:04:35 +09:00

690ae1cb57 Fix send_message(). 2011-02-04 23:49:25 +09:00

29fbc3b073 Struct and ivar declarations now seem to work. 
However, not bit-fields.
 2011-02-04 23:48:58 +09:00
Bill Currie
1f6abb2cce Minor cleanups to message_expr(). 
Fix for class names no longer being pointers to the class.
 2011-02-04 23:22:51 +09:00

eff3957487 Resurrect the address expression code for arrays etc. 
This fixes selector finding.
 2011-02-04 23:20:37 +09:00

c542e1a453 Possibly fix normal methods. 2011-02-04 22:31:23 +09:00

d0ecbb38b8 Copy the spec bits and storage class for QC functions. 2011-02-04 15:25:21 +09:00

f721144ca5 Rewrite emit_ivars to use emit_structure. 
The old code was broken anyway :) (it was segfaulting).
 2011-02-04 15:11:47 +09:00

acb3c0da11 Fix class initialization. 2011-02-04 14:29:47 +09:00

04b86fcdb7 Move the Objective-QC structs from type.c to class.c 2011-02-04 12:07:32 +09:00
Bill Currie
7b22bfba63 Better Objective-QC keyword detection. 
Use a flag in the keyword struct rather than checking for "@" in the
keyword. This catches such keywords as "id" and "Protocol" as well.
 2011-02-04 08:38:58 +09:00
Bill Currie
993bee4f59 Do not count unimplemented methods. 
The method emitter skips unimplemented methods, so counting them when
figuring out how many methods to emit leads to a segfault.
 2011-02-04 08:26:16 +09:00
Bill Currie
e04ed72afa Increment the index when emitting array elements. 
Oops :)

b07392b818 Allow ivars to use C syntax declarations. 2011-02-03 18:04:41 +09:00

dc6296e9b1 Allow ivars to use typedefs and other classes. 2011-02-03 18:03:37 +09:00
Bill Currie
2203903bb2 Temporarily splice the class's ivar chain into the symbol table. 
The root class's ivar symbol table needs to be connected to the global
symbol table while building the current class's ivar symbol table. This
allows access to other classes and typedefs.
 2011-02-03 18:02:49 +09:00
Bill Currie
79df3d2cca Put newly created classes into the symbol table. 2011-02-03 17:28:49 +09:00

564b7b9968 Use abstract_decl instead of type wherever a generic type is needed. 2011-02-03 10:53:59 +09:00
